Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed May 2, 1906'- Serial No. 314,756.

To all whom it may concern: I

Be it known that 1, JAMES S. RAMLOSE, a citizen of the United States,residing in Newport, in the county of Newport and State of Rhode Island,have invented certain new and useful Improvements in Channel- Cutters,of which the following is a description, refer ence being had to theaccompanying drawings.

My invention relates to improvements in tools for cutting a lip andgroove in leather or like material; and the object of my invention is toprovide a tool of the class described which will be simple inconstruction, susceptible of ready adjustment and certain in its action.

In the drawings illustrating the principle of my invention and the bestmode now known to me of applying that principle, Figure 1 shows the backof the tool, the parts being assembled; Fig. 2 is a view of the cuttingside or face of the tool, the parts being assembled; Fig. 3 illustratesthe tool with the cutting devices and the gage removed; Fig. 4 is asimilar view of the head of the tool; Fig. 5 is a side view of the headwith the cutting devices and the gage mounted therein; Fig. 6 is aperspective view of the groover; Fig. 7 is a like view of the gage; andFig. 8 shows a piece of leather cut by new tool.

The head a is secured in the handle I) by inserting the shank c therein,and is formed with the dove-tailed channels d, e and the recess f. Inthe latterthere is secured by the screw g a knife or cutter h the tailend of which is formed with a slot 2' which permits the knife to beadjusted to vary the depth of the cut or the width of the lip. In thegroove or channel d is slidably mounted the gage or guard j which rubsalong the top 70 of the leather and may be adjusted to vary thethickness of the lip m. In the other groove 6 is slidably fitted thegroover a formed with a hookshaped cutter 0 which serves to out thegroove 77.

Extending downwardly and outwardly from the bottom of each of thegrooves d, e is a slot g which separates and forms an ear 1* upon eachside of the head a. The resiliency of the material of which the ears rare made tends to keep the slots q open by causing the ears to springaway from the main portion 1. of the head. A screw s is passed througheach ear 1 and engages the main portion t of the head. By tightening thescrews 8 the ears r are forced in closer to the main portion t of thehead and firmly secure in place the gage j and the groover n. Byloosening the screw 8 the ear '1" is permitted by its own resiliency tospring away from the main portion t of the head and the devices slidablyfitted in the grooves d, e may then be adjusted, as will be readilyunderstood. The tenons u, 'v of the groover n and the gage jrespectively fit snugly in the grooves e, d, respectively, the walls ofthe grooves serving to hold the tenons firmly in place when the screws sare tightened.

What I claim is:

1. In a channel cutter, the combination of a head formed with grooves; aknife mounted in said head for cutting a lip; a gage mounted in one ofsaid grooves for determining the depth of the lip cut by the knife; anda device mounted in the other of said grooves for forming a groove inthe cut made by said knife.

2. In a channel cutter, the combination of a head formed with groovesfrom the bottom of which extend slots; a knife mounted in said head; agage mounted in one of said grooves; a device mounted in the other ofsaid grooves for cutting a channel in the cut made by said knife; andmeans for securing said gage and device in their respective grooves.

3. A channel cutter made up of a head formed with a groove on each sideand a recess between said grooves; a gage adjustably mounted in one ofsaid grooves a cutter having a hook-shaped end and mounted in the otherof said grooves adjustably; and a knife adjustably mounted in saidrecess between said gage and cutter.

4. A channel cutter made up of a head formed with a pair of groovesrunning in the same direction; a knife mounted in said head andadjustable in a direction at right angles to the direction of saidgrooves to vary the depth of the slit cut by it; a gage mounted in oneof said grooves and adjustable in the direction of said groove to de*termine the position of the slit formed by said knife in the leather;and a cutter formed with a hook-shaped end and mounted in the other ofsaid grooves, said cutter being adapted to cut a channel in the slitmade by said knife and being adjustable in the same direction as saidgage to vary the depth of said channel.

In testimony whereof I hereunto set my hand this 25th day of April,1906, in the presenceof two witnesses at said Newport.
